their greatest length arranged transversely of the trough and their width insufficient for permitting the average perfect bean of those being sorted to pass through them, the small beans, split ones and gravel and dirt passing through and falling upon the bottom board 19 and sliding to its lower end at 22, where they fall into any receptacle for receiving the refuse. The perforated sheet can be secured to the shaker sides with staples or otherwise. Near each end of the shaker trough, a piece 24 is secured to its bottom 19, to which the upper end of a sheet metal spring plate 25 is secured, their lower ends being secured to a post 2, and the shaker is supported upon said spring plates. Near the upper end of the shaker trough a shaft 26 is arranged for revolution in journal boxes 27 which extend to the left of the left hand post 2, and are secured thereto. The shaft is provided. with a balance wheel 28, and pulley 29 upon one end and a short throw crank 30, (about the major fraction of an inch throw), at the other end, from which a rod 31 extends to the shaker. (See Fig. 1.) This shaft being revolved at a suitable speed a series of short rapid strokes is produced and the beans as they are carried downward over the perfo rations are relieved of the imperfect and split beans and refuse to a great extent.

Upon the side edges of the posts 2 at an equal distance from their lower ends, narrow boards 32 and 32 are secured, and intermediate their ends in journal boxes 33, a shaft 34 is arranged for revolution. Upon one end of the shaft a balance wheel 35 is secured, it being provided with a crank pin 36, from which a rod 37 extends to and is connected with the treadle connecting piece 7. By operating the treadle this shaft can be revolved. The balance wheel is provided with two belt grooves 38 and 39 for round belts which are preferable in light frames. The larger pulley groove 38, has a belt 40, running to a small pulley 29 for operating the shaker and a belt 41 upon the groove 39, running to a larger pulley to be described. For assisting in feeding the beans from the hopper at a uniform rate, a loop 42 of a small wire is arranged to extend through the opening 9 in the hopper and the ends of the wire are bent around a rod 43, which is arranged above the plate 20, and across the shaker. The reciprocations of the shaker trough cause the loop 42, to continually pull the beans from the hopper into the shaker. Upon the boards 32 and 32 cross pieces 44 are arranged and upon their outer ends conveyer troughs are mounted. Figs. 1 and 8 show but one trough but Figs. 3 and 11 show how two can be arranged upon the same pair of cross pieces, and Fig. 7 shows how the cross pieces are arranged upon the boards 32 and 32 The troughs are formed of a bottom 45 and beveled sides 46, the bevels of the sides upon their lower ends being spaced from the bottom and leaving a space between said bevels and the bottom for a belt to run. At one end of the conveyer trough a shaft 47 is arranged to be revolved in journal boxes 48 and 49, one of which extends from the side 46 of trough and the other from the post 2, said shaft being provided with a pulley 50 by which it may be driven by the belt 41 from the smaller pulley upon the balance wheel shaft as before referred to. The shaft 47 is also provided with a roller 51, one or two as the number of conveyer troughs to be used in any particular machine being built requires. At the other end of each conveyer trough a similar roller 52, is arranged for revolution in journal boxes 48, each of which is attached to the conveyer trough. Around each of the two rollers of each trough a canvas belt 53, of such width as will fill the space across the trough under the beveled projections of the side pieces, is applied.

Below the conveyer trough and between the legs or posts 2, a box 54 is loosely supported upon the strips 55, which are secured to the legs. This box is for the several sorters upon each side of the machine to throw the defective beans into.

A chute 56 is arranged at the lower end of the shaker, one for each conveyer trough, for directing the beans from the shaker to the conveyers.

It should be observed that the shaker trough is quite long as compared with those in bean sorters now in use. This great length gives opportunity for the dirt and imperfect beans to fall through the slots 21, before reaching the lower end of the shaker. It should also be noticed that the conveyer trough may be one or two, as the amount of dirt in the beans and the quantity of beans to be sorted requires, and that the two conveyers are arranged alongside of the shaker, instead of in alinement with it as in bean sorters of the present construc tion. This arrangement of the conveyers. while not adding to the length of the device, permits several persons, three or four to each trough are usually employed, to sit alongside of each trough. It also permits the operating treadle board to be as long as the conveyers and be pivotally mounted at each end and be in a position to be operated by either of the persons that may be sorting upon the side of the shaker that the treadle is located. With this arrangement of shaker, conveyers and treadle, while a manually operated machine may have a capacity for employing eight sorters, its bulk and weight can be confined to the strength of a single person for carrying it from one position to another.

The operation of the device is as follows:
